The 2021 model year (MY) saw a sharp increase in the production share of light-duty hybrid electric vehicles. The production share of hybrid-electric SUVs nearly doubled from MY 2020 to MY 2021 and accounted for 4.7% of all light-duty vehicles produced. To improve fuel economy, manufacturers introduced hybrid drivetrains in MY 2000 in the sedan/wagon class. As hybrid systems have become more common, manufacturers have begun installing them in a wider array of vehicles. Hybrid pickups were introduced in MY 2018 and have seen significant growth, while the first minivan/van class hybrids appeared in MY 2021.
Note: Only hybrid electric vehicles are shown. Plug-in hybrid electric vehicles are not included in this graph.
